CCEWOOL® PCW Bulk 2912

CCEWOOL® Polycrystalline Wool Fiber Bulk is the ideal choice for high-temperature and chemically corrosive applications.

CCEWOOL® Polycrystalline Wool Fiber Bulk is made from polycrystalline mullite fibers. It can withstand a continuous operating temperature of up to 1540℃ (2800℉) with minimal shot content. This fiber exhibits excellent thermal stability and is suitable for high-temperature insulation applications. CCEWOOL® Polycrystalline Wool Fiber Bulk serves as a raw material for the production of polycrystalline fiber blankets, boards, papers, and other products.


  • Ultra-Low Shot Content

    Shot content is a crucial factor in determining the thermal conductivity of fibers. Using imported high-speed centrifuges, our fibers achieve ultra-low shot content, demonstrating excellent thermal performance with low thermal conductivity and superior insulation properties in continuous high-temperature environments.

  • Minimal Shrinkage Rate

    Strict control of harmful impurities is essential for reducing thermal shrinkage and enhancing heat resistance. Through rigorous raw material management, we reduce impurity content to below 1%, ensuring low thermal shrinkage and high heat resistance in our fiber modules.

  • Lowest Thermal Conductivity

    Through strict quality control and high-standard production processes, CCEWOOL® minimizes shot content, achieving the lowest thermal conductivity. This provides customers with exceptional insulation performance and more efficient energy-saving solutions.

  • Versatile Applications

    Can be used as raw material for RCF blankets, boards, and paper, or directly for high-temperature insulation and various other high-temperature applications.

Features of Polycrystalline Wool Fiber Bulk

  • Excellent Thermal Shock Resistance

    CCEWOOL® PCW Bulk 2912 can withstand rapid temperature changes without cracking or degrading, ensuring reliable performance in environments with fluctuating temperatures.

  • Excellent Chemical Stability

    This bulk material exhibits excellent chemical stability, maintaining its properties and performance even when exposed to harsh chemicals, ensuring long-term durability and reliability.

  • High-Temperature Stability

    The material maintains its structural integrity and performance at high temperatures, providing consistent and reliable insulation in extreme heat conditions.

  • Low Thermal Conductivity

    CCEWOOL® PCW Bulk 2912 has low thermal conductivity, which minimizes heat transfer and enhances energy efficiency, making it an excellent insulator for high-temperature applications.

  • Low Shot Content

    This bulk material has a low shot content, which means it contains fewer non-fibrous particles. This improves the overall quality and performance of the insulation, ensuring better thermal and mechanical properties.
